Motor systems often require that superfluous degrees of freedom be constrained. For the oculomotor system, a redundancy in the degrees of freedom occurs during visually guided eye movements and is solved by implementing Listing's law and the half-angle rule, kinematic constraints that limit the range of eye positions and angular velocities used by the eyes. These constraints have been attribute...

A graph G with at least 2k vertices is k-path pairable if for any k pairs of distinct vertices 9f G there are k edge disjoint paths between the pairs. It will be shown for any positive integer k that there is a k-path pairable graph of maximum degree three.

the investigations were carried out in 2007 on the fruit of 7 native early-ripening apple cultivars grown in karaj climatic conditions, harvested in two phenological stages of maturity and ripenning. the harvested samples were stored at (0 ± 0.5) c and (85 ± 5) % of humidity. the measured sensorial traits consisted in: aroma, flavor, sweetness, flesh quality and general acceptability achieved ...

Foodborne diseases affect millions of people each year. To reduce the incidence of bacterial foodborne pathogens more effective treatment methods are needed. In this study, we evaluated the effect of marinating chicken breast fillets with extracts of lemon, green tea and turmeric against Campylobacter jejuni and Salmonella enteritidis. The prepared plant extracts in phosphate buffered saline we...

In situ volumetric soil-water contents were measured on 11 days at 0.20 m depth intervals to 1.0 m in a field experiment with four replicates of a dry-land corn hybrid (Pioneer 3140) at plant populations of 37, 49, and 62 thousand plants haÿ1. These measurements were used to estimate total soil-water losses in each of the 12 field plots for each of the 10 measurement intervals. The area of the ...

background : the present study aimed to investigate the rate and time of ovarian function restoration in breast cancer patients between 40 and 60 years of age who were in menopause (biochemically documented) and received letrozole after chemotherapy. we intended to further clarify the management strategy for breast cancer patients with different menopausal status. methods : we prospectively mea...

 Analysis of the characteristics of precipitation fields;  Sampling of precipitation fields at different regular and irregular steps of grid and different time intervals;

Immunoglobulins (Ig) and some complement components (C) were quantified in sera from patients with gastric carcinoma before surgery and at regular intervals during a 5-year follow-up.
